Abstract

This trial was designed to evaluate the influence of hatching egg storage length and broiler breeder hens' age on post-hatch growth performance and physiological responses of FUNAAB-α chickens. Five hundred fertile eggs from each of 60 and 32-wk-old FUNAAB-α breeder hens were collected and assigned to five storage durations (0, 3, 7, 11, and 15 d). The hatching eggs were incubated using the conventional protocol. Data were collected on the growth performance and physiological responses. A 2 × 5 factorial design was used for the experiment. The results revealed that there was a decline in the final body weight in chickens from eggs of 15 and 11 d storage compared to the chickens from 7, 3, and 0 egg storage days. Chickens of 32-week-old breeder hens had higher (P < 0.05) mean corpuscular volume, white blood cell, heterophil, and pack cell volume values compared to 60-week-old breeder hens. Hatchlings from 60-week-old breeders had a higher liver percentage (3.0% yolk-free body weight [YFBW]) than those from 32-week-old breeders (2.8% YFBW). It was concluded that an extended storage duration of 15 d adversely affected the carcass traits and growth performance of chickens from egg storage above seven days.

种鸡年龄和孵化蛋储存时间：对 FUNAAB- α 肉鸡孵化后性能的影响。

本试验旨在评估孵化蛋储存时间和肉用种鸡年龄对 FUNAAB-α 鸡孵化后生长性能和生理反应的影响。从 60 周龄和 32 周龄的 FUNAAB-α 种鸡中各收集 500 枚受精蛋，并将其分配为五种贮存期（0、3、7、11 和 15 天）。孵化鸡蛋采用常规方法孵化。收集了有关生长性能和生理反应的数据。实验采用了 2 × 5 的因子设计。结果显示，与储蛋 7 天、3 天和 0 天的鸡相比，储蛋 15 天和 11 天的鸡最终体重有所下降。32 周龄种鸡的体重（P

期刊介绍： Translational Animal Science (TAS) is the first open access-open review animal science journal, encompassing a broad scope of research topics in animal science. TAS focuses on translating basic science to innovation, and validation of these innovations by various segments of the allied animal industry. Readers of TAS will typically represent education, industry, and government, including research, teaching, administration, extension, management, quality assurance, product development, and technical services. Those interested in TAS typically include animal breeders, economists, embryologists, engineers, food scientists, geneticists, microbiologists, nutritionists, veterinarians, physiologists, processors, public health professionals, and others with an interest in animal production and applied aspects of animal sciences.
